Abstract:
A cooling system for cooling a heat source and a projection apparatus having the same are disclosed. The cooling system includes a heat dissipating device and a thermoelectric cooler (TEC). The heat source is disposed on the side of the heat dissipating device. The TEC is disposed on the other side of the heat dissipating device corresponding to the heat source. The TEC is initiated as the temperature of the heat source is greater than the first value, while the TEC is shut off as the temperature of the heat source is lower than the second value. Therefore, the cooling system economizes the energy by controlling the operation of the TEC according to the temperature of the heat source.
